Hello. Are you saying you can't find the Lightroom 3 serial number you already have?
If that is the case you should be able to find the serial number directly in the LR software itself. Usually Adobe products let you view the serial number you used when you installed the software.
Yes you need the original serial from LR# XXXXX order to activate the v4 upgrade. I have 3 ways you can get your LR3 serial number:
1.) If you registered the software with Adobe when you installed it then you can log in to your Adobe account and recover the serial number there.
2.) You can use utilities such as Belarc Advisor to recover serial numbers from the registry of the desktop which you said you have LR3 installed on, Download Here3.) This one may or may not work for your version depending how it was installed. On the desktop look for the 'Lightroom 3.0 Registration.lrreg' file. If you have that file it should contain the LR3 serial number, open it with a text editor, and you'll see 'original_serial_number =' and/or 'serial_number ='
The location of the .lrreg file can be different depending on your o/s, heres a list from Adobe where it should be: .lrreg Locations
I haven't been able to find the location from any menu. I am on a mac OSX, by the way...
Also can't download Belarc Advisor from your response...
Apparently I didn't register with Adobe. I believe I bought LR 3 from Apertures photography, a local photog. store where I live.
Sorry. I'll need more directions. I made it all the way to Library once but was closed out from further selection... Here's what I finally got.
original_serial_number serial_number uuid XXXXXXXXXXXXXXXXXXXXXXXXXXX
Is the XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX not the serial number you were looking for?
It does not appear to fit into the boxes at all. Each box has 4 spaces and there are 6 in all.
The only one available when I reached the last folder in Adobe Lightroom Library. There were no more choices available save the one I copied to you.
Oh, but wait. The only way I found Lightroom was clicking "application support". Nothing else under applications led me to Lightroom....
Just a thought, above where Chris had you goto the library and user files, OS/X 10.7 & later hid the user lib files by default, you need to unhide to get to the directory you need. If you need help getting to the hidden dirs, here's the Adobe OS/X Hidden Dir Page.
<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"><plist version="1.0"><dict><key>original_serial_number</key><string></string><key>serial_number</key><string></string><key>uuid</key><string>4BB41614-0A16-45F1-8C13-A6F806160279</string></dict></plist>
This is what is in the ~/Library folder. It is not a useable serial.
To you it's not usable, if you contact Adobe and tell them you have this file & key string and what your issue is, they can decrypt it to a usable key. Or they'll claim they can't verify or identify you as the owner but, they will most likely give you the option to send them proof of purchase and will issue you an upgrade key.
Depending on who you get when you contact support, they may give you hassle, don't be afraid to throw a little muscle. Let them know you can very easily find another software package if their not interested in your business. I've done it, sometimes you hafta get tough.
Whatever I get or don't get, thanks for an amazing try! I am giving you top rating. The person you referred me to sent me the "18 ways you can access your Library" from MacWorld or the like...loser answet!
I rated you top rating and authorized a tip.
Now, here is the answer: When I loaded LR4 on my desktop and entered the upgrade serial #, my LR3 serial number loaded below it, automatically. When I took the upgrade to the laptop which had crashed and lost LR3 I put in the new serial and when prompted, entered the old LR3 # XXXXX I had been given. All done!
Glad everything worked out for you, happy to be a part of the solution. Come back anytime you need assistance.
